I just don't understand what is going on here. I have the following code
var dragChild:UIComponent = UIComponent(event.currentTarget);
var ds:DragSource = new DragSource();
ds.addData(dragChild.parent, 'dragParent');
ds.addData(dragChild, 'dragChild');
var proxy:UIComponent = UIComponent(event.currentTarget);
var bitmapData:BitmapData = new BitmapData(proxy.width, proxy.height);
bitmapData.draw( proxy );
var bitmap:Bitmap = new Bitmap( bitmapData );
var image:Image = new Image();
image.source = bitmap;
// Call the DragManager doDrag() method to start the drag.
DragManager.doDrag(dragChild, ds, event, image);
The problem throws an error on the last line saying
A term is undefined and has no properties
And then opens up the AdvancedDataGrid.as file and shows me this line.
public function get firstVisibleItem():Object
{
--> return listItems[0][0].data;
}
Why am I getting an error thrown, and why is it being thrown in the
AdvancedDataGrid.as file. I am not doing anything with the
AdvancedDataGrid. Just using Panels, Canvas, Vbox, and UIComponent.
If I comment out all the addData lines there is no error thrown, so it has
something to do with what I'm putting in the Datasource. I also checked
those variables and they seem ok.
Any ideas?
